MUSIC-ROLL-BOX CLIP.

Application filed J'une 14, 1923.

To all whom t may conce/fa.'

Be it known that I, THOMAS M. FLETCHER, a citizen or' the United States, having residence at Fontana, in the county of Nalworth, in the State of lViscOnsin,l have invented certain new and useful Improvements in Music-Roll-Box Clips, of which the ollowing is a specification, reference being had to the accompanying drawings, forming a part thereof. n

The purpose of this invention is to provide an improved device in the nature of a clip for application to the edge of a box for containing` spooled sheet material to hold the sheet from unwinding or slacking on the spool, being particularly designed 'lor applying to a music roll box to hold the coiled note sheet against uncoiling or slacking in the box. It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings Figure l is a top plan View of a music roll box partly broken away disclosing the music roll therein and the clip embodying this invention.

Figure 2 is a section at the line 2-2 on Figure l.

Figure 8 is a perspective view of the clip in one form.

Figure 4 is a perspective view of the clip in a slightly modified form.

Figure 5 is a view showing Figure 4 from the opposite side.

Figure 6 is a section at the line 6-6 on Figure 5, on an enlarged scale.

In the drawings the roll box is shown at A, the music roll spool therein is shown at B, with the note sheet, C, coiled thereon. The device which constitutes this invention is a sheet metal clip, D, made from a ribbon of sheet metal cut into short strips,-in length about once and a halt the depth of the box, A. A short portion, CZ, at one end of the strip is relexed upon the strip to form a hook, D1, whose two sides are spaced apart suiiiciently to admit the side of the box between them, that is,-into the recess or loop of the hook, and to cause the hook to grip the box side securely when the clip is thus applied thereto. At a point Z2 of the length of the strip located as far from the bend, (Z1, of the U-clasp or hook terminal, D1, as the length of the hook terminal, d, the strip is flexed definitely inward with re- Serial No. 645,231.

y form a smooth blunt terminal as seen at d2.

For stiffening the device at the bend, d2, there is formed a corrugation, (Z3, extending crosswise of said bend at the inner side thereof.

For improving the grip of the hook or U-clasp, D1, on the side of the box, and partly to prevent it from slipping too easily on said side, both limbs or sides of the clasp or hook may be corrugated longitudinally, i. e. transverse the bend or fold, d1, by which the hook is formed,-such corrugations shown at (Z4, Figures 4L and 5, being preferably not abrupt, but only such as render the corrugated part sinuous as seen most clearly in Figure 6, the sinuousity o the two sides of the hook being parallel so that they render the portion of the box edge on which the clip is clasped similarly sinuous without liability to rupturing the pasteboard in applying the clip thereto.

Wvhen this clip is applied to the box it will be understood that the insertion of the music roll into the box causes the spring linger D2, of the clip to be crowded back toward the side of the box and to press with some force yieldingly against the note sheet coiled on the spool preventing it from unceiling.

It will -further be observed that the form of the clip being made of thin sheet metal as indicated, is such that it does not intertere with applying any sort of cover to the box or telescoping the box into an exterior case.

I claim:

l. In combination with a music roll box and the like container, a clip for checking the roll content of the box against slacking on and uncoiling from the spool, consisting of a piece of sheet metal folded upon itself at one end forming a hook for closely clasping the edge of one side of the box and iiexed off from the plane of the hook recess inward with respect to the box cavity,

said flexure being made at a distance from the bend which forms the hook sufficient for rendering the depth of the hook adequate to secure a grasp upon the boX edge; whereby the remainder of the length from said fleXor to the limit permitted by the depth of the box forms a spring linger for pressing against the roll.

2. In the` Construction defined in claim 1 foregoing, the inner limb of the hook being stiffened at the liexure by a eorrugation extending transversely of said l'leXure and projecting inwardly with respect to the boX cavity.

3. In the Construction defined in claim l foregoing, the spring linger Within the box being reeurved back toward the box side with which the clip is engaged lfor presenting to the roll a face Convex in vertical plane transverse the roll.

4. In the Construction defined in claim l foregoing, the hook portion of the clip havn ing one of its parallel sides longitudinally corrugated so as to be sinuous in crossseetion.

5. In the construction defined in claim 1 foregoing, the hooky portion of the clip having both of its hook sides, longitudinally corrugated so as to be sinuous, the sinuousity of the two sides being substantiallyparallel with eaeh other.
